Sewing thread is not often used, but it is always available, and we do not know what material it is when we use it. Polyester sewing thread is the thread we use the most, let’s learn more about it together!
Sewing thread is the thread required for knitted clothing products. Sewing thread can be divided into three categories according to raw materials: natural fiber, synthetic fiber sewing thread and mixed sewing thread. Sewing thread uses pure polyester fiber as its raw material.
Polyester sewing thread is a sewing thread produced from polyester as raw material. Also called high-strength thread, nylon sewing thread is called nylon thread, we usually call it polyester sewing thread, which is twisted with polyester long fiber or short fiber, wear-resistant, low shrinkage, and good chemical stability. However, the melting point is low, and it is easy to melt at high speed, block the needle eye, and easily break the thread. Due to its high strength, good wear resistance, low shrinkage rate, good moisture absorption and heat resistance, polyester thread is resistant to corrosion, not easy to mildew, and not moth-eaten, etc. It is widely used in garment sewing of cotton fabrics, chemical fibers and blended fabrics due to its advantages. In addition, it also has the characteristics of complete color and luster, good color fastness, no fading, no discoloration, and sunlight resistance.
The difference between polyester sewing thread and nylon sewing thread, polyester ignites a lump, emits black smoke, smells not heavy, and has no elasticity, while nylon sewing thread also ignites a lump, emits white smoke, and has a stretchy smell when pulled Heavier. High wear resistance, good light resistance, mildew resistance, coloring degree of about 100 degrees, low temperature dyeing. It is widely used because of its high seam strength, durability, flat seam, and can meet the needs of a wide range of different sewing industrial products.
In production and processing, polyester thread is generally divided into the following three categories of uses:
1. Weaving yarn: Weaving yarn refers to the yarn used for processing woven fabrics, which is divided into two types: warp yarn and weft yarn. The warp yarn is used as the longitudinal yarn of the fabric, which has the characteristics of large twist, high strength and good wear resistance; the weft yarn is used as the transverse yarn of the fabric, which has the characteristics of small twist, low strength, but softness.
2. Knitting yarn: Knitting yarn is the yarn used in knitted fabrics. The yarn quality requirements are high, the twist is small, and the strength is moderate.
3. Other yarns: including sewing threads, embroidery threads, knitting threads, miscellaneous threads, etc. According to different uses, the requirements for polyester yarn are different.
